Xi's anti-corruption drive in focus as China's party plenum opens

China's Communist Party opens its fifth plenum on Monday, set to focus on "advancing the party's full and rigorous self-governance", according to state media, a phrase signalling discipline, loyalty and anti-corruption. Since taking power in 2012, Xi Jinping has kept up his crackdown: last year, more than one million people were investigated, including over 100 ministerial or provincial-level officials.
